Acoustic signals mediate interactions among signalers and the destined receivers. While immersed in multisource background noise, deleterious effects for species fitness can emerge by signal interference and confusion. Because acoustic signals are involved in competition and reproduction success, character displacement can emerge based on the role of background noise components as selective pressures. In this sense, species can partition the acoustic space in the spectral and temporal domains to avoid signal overlap. Likewise, environmental structure can operate as a filter for signal propagation. Contrary to the viewpoint of acoustic space as a competing resource, signals can mediate interactions among species in communication networks, especially among ecologically similar species. Here, we propose to use anuran assemblages of the Pantanal wetlands to investigate three possible processes that generate acoustic differences within assemblages: partitioning of the acoustic space, acoustic adaptation to the environment, and species interactions in communication networks. We envisage three scenarios for the acoustic structure and taxonomic relatedness of the signaling assemblage: i) partitioning of the acoustic space leads to high acoustic variability and low species relatedness; ii) acoustic adaptation to the environment leads to low acoustic variability and no structure on relatedness; iii) species interaction in communication networks leads to low acoustic variability and high species relatedness. To assess whether acoustic differences are important on species assembling or not, we will investigate the role of acoustic differences and habitat structure on determining species turnover under a deterministic framework. An investigation on the assemblage scale could reveal whether the observed acoustic space is an outcome of species competition or not, and the extent on which species assembly is conditioned by acoustic differences.
